無法從主站連接到從站。 「遇到無效的編碼序列：」

我在AWS EC2實例中有Box Master和Box Slave。我在Box Slave中創建了jenkins用戶，我將master's公鑰複製到slave。現在我在Jenkins Master中創建了一個新的node。但是，當我連接使用Launch agent via execution of command on master使用命令ssh -tt [email protected]到從，它給了我下面的錯誤：無法從主站連接到從站。 「遇到無效的編碼序列：」

just before slave Services-Slave gets launched ... 
executing pre-launch scripts ... 
[06/26/17 16:25:28] Launching agent 
$ ssh -tt [email protected]

如果我從username運行相同的命令從master它能夠ssh成功。任何想法爲什麼發生這種情況？

  1. 我試圖給.pem文件
  2. 我也沒有sudo -u jenkins。什麼都沒有
